[1.12][1.11.x][1.10.2] Looking for a collection that contains all registered IBlockStates

[OreCruncher]

Is there a collection kept somewhere that has all the registered IBlockStates?  I figured there has to be one - just can't find it for some reason.  Maybe I need more coffee.

No, there isn't.

There's a list of all Blocks, but each block maintains its own list of valid states.

[OreCruncher]

So I could do something like traverse the Block registry calling getBlockState() on each entry, and then iterating over getValidStates() result.

If you really need to...yes

Question is ...why?

[OreCruncher]

I am adding some diagnostic code to my mod that will cross check the registered IBlockStates with the mods configuration.  I want to identify blocks that don't match any rules in the configuration.  It's a niche need.
